EU Exit Negotiations

Yesterday, our Prime Minister was humiliated by having the rug pulled from under her by the DUP. Was she not naive even to attempt to do a deal of the sort she tried to do, knowing that the DUP would inevitably veto it? With the negotiations in such fantastic hands, will the Secretary of State now admit that the only way to move forward without a hard border in Northern Ireland, to protect the jobs of my constituents, is for us to stay in the customs union and the single market?
